    Notes

  • Should be reseeded every year.
  • Sweetclover contains coumarin (which is an aromatic, bitter tasting compound) and coumarin toxicity may develop when mold or heat (when hay is baled wet) convert coumarin to dicoumarol (an anticoagulant).
  • Low-coumarin cultivars are being developed.
  • Sweetclover is found growing in a wild state throughout Florida, where soil conditions are suitable.
  • Graze at height of 8-10 inches and stop grazing when at 3-5 inches; rest period: 10-20 days.
